Lead is a well-known health hazard, and it is important to be aware of its presence in plastic products, especially those intended for children. Lead is sometimes added to plastic to make it more flexible and soft, and to stabilize molecules from heat exposure. However, when plastic containing lead is exposed to sunlight, air, or detergents, the chemical bond between the lead and plastic breaks down, forming a dust that can be ingested, leading to lead poisoning. This is of particular concern in children's toys, as young children often put things in their mouths. Lead can also be found in imported candies, folk medicines, jewelry, and vintage products. To test for lead in plastic, a certified laboratory test is required, as DIY kits are unreliable.

What You'll Learn
Lead in plastic toys
Lead is a known health hazard and its use has not been banned in plastics. Lead is used to soften plastic and make it more flexible. It is also used in plastic toys to stabilise molecules from heat. When exposed to sunlight, air, or detergents, the chemical bond between lead and plastic breaks down and forms a dust. This is a particular risk for children, who may touch the toy and then ingest the dust by putting their fingers in their mouths.
Vintage plastic toys frequently contain toxic heavy metals, especially lead, at concentrations exceeding current safety limits. Older toys are likely to have degraded over time, releasing small plastic particles and toxic metals. The developing brains and bodies of infants and young children are particularly vulnerable to toxic exposures as they absorb and retain lead more efficiently than adults. Passing on childhood toys to the next generation may seem touching, but research has found that vintage toys can contain alarming levels of lead. A study of plastic toys from the 1970s and 1980s found that one in four contained more than ten times the current safety limits for lead.
Toys that have been made in other countries and then imported may also contain lead, as it is still widely used in paint in other countries. Lead may be found in the paint on toys imported to countries where lead paint has been banned. Lead is also used in alloys with other elements such as antimony, tin, arsenic, and calcium, which may be used in toys. Lead may be found in vintage toys purchased at thrift stores, flea markets, garage sales, antique shops, or online.
Many dangerous toys have been recalled, but lead has been found in some toys that have not made any recall list. It is recommended that parents check the Consumer Product Safety Commission (CPSC) website for recalls and sign up for email alerts about future recalls. For toys that are not on the recall list, home lead-test kits can be used, although these may not always be accurate. For the most accurate results, parents should send suspect items to a lab or visit their county health department.

Lead in candy and folk medicine
Lead is sometimes found in certain international foods, cosmetics, and traditional medicines. Lead in candy, folk medicine, or cosmetics cannot be detected by looking at or tasting it. Testing products in a laboratory is the only way to tell for certain if the product contains lead. Lead has been found in some candies, with certain ingredients such as chilli powder and tamarind being sources of lead exposure. Improper drying, storing, and grinding of ingredients can cause lead contamination. Lead may also be present in the ink on plastic or paper candy wrappers, which can seep into the candy.
Folk and traditional medicines can contain herbs, minerals, metals, or animal products believed to be useful in treating ailments. Lead and other heavy metals may be intentionally added to folk medicines or accidentally introduced during grinding, colouring, or packaging. Ghasard, an Indian folk medicine, is a brown powder used as a tonic that has been found to contain lead. Greta and Azarcon, Hispanic traditional medicines, are orange powders with lead content as high as 90%. Ba-baw-san, a Chinese herbal remedy, and Daw Tway, a digestive aid used in Thailand and Myanmar, have also been found to contain high levels of lead.
Lead exposure poses a significant health risk, especially to children, who are a vulnerable population. Lead can be found in plastic toys, vintage toys, and children's jewelry, increasing the risk of exposure through chewing, sucking, or swallowing. The chemical bond between lead and plastics can break down when exposed to sunlight, air, or detergents, forming a dust that can be ingested. Lead was also found in artificial turf playing fields, posing a potential public health concern.
To prevent lead exposure, it is recommended to avoid using products that may contain lead and to be cautious when purchasing vintage or imported items. If lead exposure is suspected, a healthcare provider can advise on the need for a blood lead test and recommend appropriate follow-up actions.

Lead in paint
Lead is a well-known health hazard, particularly for children. Lead was banned in house paint, on products marketed to children, and in dishes or cookware in the United States in 1978. However, it is still widely used in other countries and can be found on imported toys and products. Older toys and products manufactured before 2009 may also contain lead-based paint or higher levels of lead in their materials.
If you suspect that a toy or product may contain lead, it is important to remove it from a child's possession immediately. The only accurate way to test a toy for lead is by sending it to a certified laboratory. While do-it-yourself kits are available at hardware stores, they do not indicate whether toys are safe for use. Blood testing is the only reliable way to determine whether a person has been exposed to lead.
If you are concerned about lead in paint in your home, you can purchase a lead testing kit to check for lead. Klean-Strip D-Lead Paint Test Kits and 3M Lead Check Swabs are two types of lead testing kits that bear the EPA's seal of approval. These kits can be purchased online or at a hardware store for around $20-40. When testing for lead in a home that hasn't been renovated since 1978, be sure to test each room separately to ensure that no contaminants are missed.
If you are unsure about how to test for lead or interpret the results, you can always call your local city or county office to have a professional come out and test for lead in your home. It is important to take precautions and seek appropriate guidance to ensure the safety and well-being of yourself and your family.

Lead in jewelry
Lead is often used in jewellery, including children's jewellery, to make the product heavier, brighten colours, and stabilise or soften plastic. Jewellery labelled as made in the United States is less likely to contain lead compared to jewellery made abroad. There is an increased risk of buying lead-based jewellery from informal and unregulated sources. Lead exposure can occur through ingestion, inhalation, or absorption through the skin, with children being particularly at risk due to behaviours such as chewing or sucking on jewellery.
While absorption of lead through the skin from wearing jewellery is considered less likely to pose a significant risk, it is still important to take precautions, especially for children. Children should not be allowed to wear jewellery that may contain lead to prevent exposure through chewing, sucking, or swallowing. Lead is a well-known health hazard and can cause serious health issues, especially in children.
In terms of identifying lead in plastic, it is important to understand that the use of lead in plastics has not been banned. Lead is added to plastic to soften it, increase flexibility, and stabilise molecules from heat. However, when the plastic containing lead is exposed to sunlight, air, or detergents, the chemical bond between the lead and plastic breaks down, forming a dust that can be ingested or inhaled. This is particularly concerning in children's toys, as they may touch the toy and then put their fingers in their mouths, ingesting the lead dust.
To minimise the risk of lead exposure from jewellery, it is recommended to purchase solid gold jewellery or items from verified vendors. Additionally, avoiding cheap costume jewellery found at stores like Claire's can help reduce the likelihood of lead exposure. It is also important to be cautious when purchasing antique or vintage jewellery, as older pieces may contain lead-based paint or higher lead levels in the materials.
Overall, while lead in jewellery is a concern, the risk of exposure can be mitigated by making informed purchasing decisions and being aware of the potential hazards associated with certain types of jewellery.

Testing for lead
Lead is a well-known health hazard, and exposure to it can cause health issues like depressed intelligence, irritability, insomnia, infertility, and even death in large doses. It is often used in consumer products such as candy, folk and traditional medications, ceramic dinnerware, children's jewelry, clothing ornaments, children's toys, key chains, vinyl, plastic, rubber, and metallic products.
If you suspect that a plastic product contains lead, there are a few ways to test for its presence:
- Visual Inspection: While lead itself is invisible and has no smell, you can look for signs of degradation in the plastic. Over time, exposure to sunlight, air, and detergents can break down the chemical bond between lead and plastics, forming a dust that may be visible.
- Do-It-Yourself Kits: DIY lead testing kits are available at local hardware stores. However, it is important to note that these kits may not provide a definitive indication of the safety of the product. They may give you a preliminary idea but are not entirely reliable.
- Certified Laboratory Testing: The only accurate way to test a plastic product for lead is by sending it to a certified laboratory. They will have the specialized equipment and expertise to detect lead accurately.
- Blood Testing: If you are concerned about potential lead exposure, especially for children, consult a healthcare provider. They can recommend and perform a blood lead test to determine if there are elevated levels of lead in the body. Blood testing is the most reliable way to assess lead exposure and poisoning.
It is important to be vigilant about potential sources of lead exposure, especially for children, who are more vulnerable due to normal hand-to-mouth activities and the tendency to put objects in their mouths during development. Stay informed about product recalls, and avoid purchasing or using older, antique, or imported toys and consumer products that may contain lead.
