Children's health

Last month, 14 children between the ages of two and six lost their lives to pesticide poisoning in Bangladesh after eating contaminated litchi (or lychee) fruit.

As reported by the Bangladesh daily New Age, the specific pesticides responsible have not yet been identified. But samples of the poisonous fruit are currently being tested by the Center for Disease Control & Prevention in Atlanta.

Lice shampoos containing lindane continue to be allowed in the U.S., despite being slated for a global ban due to the organochlorine pesticide's persistence and toxicity. Last week, Representative Edward J. Markey (D-MA) urged the Obama Administration to pull these products from the U.S. market once and for all.

In 2009, more than 160 nations agreed to ban the agricultural uses of lindane, and to phase out pharmaceutical uses around the world by 2014. Lindane shampoos and lotions have been banned in California since 2002, and several other states have moved to severely restrict the use of these products.

There's an interesting debate emerging in the public health world. It has to do with whether we need to rejigger our thinking about the risks pesticides and other chemicals pose to children's health.

Traditionally, we've had a "disease-oriented" approach, assessing risk based on the severity of a health outcome (think birth defects or cancer). But earlier this month a provocative Environmental Health Perspectives article argued that a "population approach" might be wiser — meaning that even when a health effect is not severe, if it's affecting a huge number of our children (think dropping IQs), we should be paying attention.

The "obesity epidemic" is constantly in the news. This year's CDC figures show that 1 in 88 children in the U.S. is on the autism spectrum. Childhood cancers and neurodevelopmental delays are on the rise.

Scientific studies show that many of these health conditions can be linked to exposures to environmental contaminants such as pesticides, and new research is finding that exposures occurring as far back as three generations can cause adverse health conditions today.

Part of my job here at PAN is keeping track of the latest research about how pesticides are harming children’s health. This has kept me too busy of late, as studies seem to be coming fast and furious linking pesticides with childhood asthma, autism, birth defects, cancer and more.

One recent study gave me serious pause. We already understand that some chemicals can change how our genes function; now researchers know that this damage can be passed from one generation to the next. I’m no scientist, but I understand enough to know that compromising the DNA of future generations is not a good idea.
