A recent scientific report from Turkey studied the developmental effects on Zebrafish (Danio rerio) when they are exposed to deltamethrin. Survival rate, hatching, and body malformations were determined after deltamethrin exposure.
The study results showed that DM (deltamethrin) cause body malformations, mortality and and delay hatching, survival rate decreased, and apoptosis increased.

The figures above show how survival rate decreased with the concentration of deltamethrin, and malformations increased with concentration.
Deltamethrin easily enters waterways through runoff, which is why it is important to know how Deltagard is affecting our ecosystems. This is also why Deltagard instructions say to not spray the product directly on or adjacent to a waterway. But how can we be sure that when Deltagard trucks spray our lawns and streets in the borough, the poison does not run into the storm drains and affect our wildlife? Also, if deltamethrin has such detrimental effects on zebrafish, who’s to say what unknown effects if may have on insects, birds, dogs, and even humans? As always, it’s better to be safe than sorry. Reduce your use of Deltagard on your property, and express to the county that you are concerned about the use of Deltagard throughout the borough.

According to Chester County Coroner Dr. Christina VandePol (download the Aug. 2 press release here),
The Chester County Coroner’s Office is releasing data on drug overdose deaths in Chester County from January 1, 2019 through June 30, 2019. A total of 65 people have been confirmed to have died of a drug overdose during this period, with 62 deaths determined to be accidental and 3 due to suicide. …
Something seems amiss in how the County organizes its services! The Health Department does not deal with this major health epidemic, but when you look at the Health Department home page you find under “Environmental Services”:
What does the spotted lanternfly have to do with human health? Why does the Health Department spend $200,000+ a year on mosquito control when the chief mosquito-related health problem it cites, West Nile Virus, has never caused one fatal case acquired in Chester County, compared to thousands of fatal opioid overdoses?
In the Health Department’s “A-Z Health Topic List,” you can find bats and dog licenses, and even Zika Virus (which is not transmitted by insects this far north), but no link to information about an epidemic that is killing an average of 2.5 people a week in Chester County! (You’d think Drug and Alcohol Services would feature itt, but good luck finding even one reference to fentanyl there.)
Why doesn’t the County have an Environment Department, with trained experts in environment and sustainability, to deal with concerns like over-proliferation of some species and existential threats to others, climate change, excessive water runoff, stream erosion, air and water pollution, environmental degradation from trash and especially single-use plastics, renewable energy, and so much more?
Then the Health Department could focus on its job: health.
Green America, an environmental organization, conducted a report exploring environmental initiatives in leading clothing stores. The report looked at 14 major apparel companies to see if they were addressing issues like chemical use and waste from clothing production.
One of the features they checked was chemical management. Directly from their report, which can be found here:
The production of textiles uses an estimated 43 million tons of chemicals every year – and this figure doesn’t even take into account the amount of pesticides used to grow natural resources, such as cotton, annually.
Chemicals are used heavily throughout the production of textiles – the process of turning raw materials into textiles uses over 8,000 different chemicals. The Swedish Chemicals Agency tested 2,400 chemicals and found that about 30% of them were toxic. While some chemicals have been banned/restricted in consuming countries, that chemical may be found in waterways of the manufacturing country, exposing not just workers to these hazardous chemicals, but also the community at large.
Industry-wide, there is a need for more transparency and data about the chemicals that are being used, as well as their effects on health and the environment throughout the life cycle of the textile/garment . . .
Until companies become more transparent about their chemical use, it’s hard to know what you’re truly paying for when you purchase clothing. Green Team’s advice to you is to purchase new clothes only when absolutely necessary – and to use the clothes you already have as long as possible.
