The agency recommended that DEET-based products be used on children between the ages of 2 and 12 only if the concentration of DEET is 10% or less and that repellents be applied no more than 3 times a day, children under 2 should not receive more than 1 application of repellent in a day and DEET-based products of any concentration should not be ...
[15] [40] [41] Despite concerns emerging in the scientific community, and lack of research, the FDA considered it safe up to 7 parts per million in food. There was a large economic incentive to push DDT into the market and sell it to farmers, governments, and individuals to control diseases and increase food production.
Dichlorodiphenyldichloroethylene (DDE) is a chemical compound formed by the loss of hydrogen chloride (dehydrohalogenation) from DDT, of which it is one of the more ...
Little is known about the chronic toxicity of diethyl phthalate, but existing information suggests only a low toxic potential. [6] Studies suggest that some phthalates affect male reproductive development via inhibition of androgen biosynthesis.
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
1-Octen-3-ol, octenol for short and also known as mushroom alcohol, [1] is a chemical that attracts biting insects such as mosquitoes.It is contained in human breath and sweat, and it is believed that insect repellent DEET works by blocking the insects' octenol odorant receptors.
This improper name persists, especially in elementary textbooks. In biology, the unit "%" is sometimes (incorrectly) used to denote mass concentration, also called mass/volume percentage. A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because ...
2,5-Dimethylfuran serves as a scavenger for singlet oxygen, a property which has been exploited for the determination of singlet oxygen in natural waters.The mechanism involves a Diels-Alder reaction followed by hydrolysis, ultimately leading to diacetylethylene and hydrogen peroxide as products.
