The Dangers of Genetically Modified Foods Despite the recent surge in media coverage regarding genetically modified foods (GM foods) many Americans are unaware of what these foods are‚ or the possible benefits and dangers associated with them. Sometimes referred to as agricultural biotechnology; genetic modifying means that the DNA of food has been altered in some way at a cellular level. Scientists have learned that by inserting the genetic information from one organism into another they can

This report also showed that there were also very high rates of toxins put into the air such as cardiovascular or blood toxins‚ kidney toxins‚ and endocrine toxins. All of these categories were also showing in the 40 50 percentile range. There were also reports of air releases of recognized carcinogens which were a little higher in the 50 60 percentile range

Powerful toxins produced can travel through the food web of a marine ecosystem and affect seabirds‚ marine animals and humans‚ which potentially can be fatal (Seaweb‚ 2). Humans can contract aliments from the algae as well‚ by breathing air borne toxins by coming in contact with it physically or consuming contaminated shellfish. There are two types of toxins produced by Microcystis: Neurotoxins and Hepato-toxins These toxins affect surrounding ecosystems‚ and more

Another reason Lake Erie’s water is polluted is due to toxins. First‚ there is a lot of bacteria entering Lake Erie. A few years ago much of Lake Erie was very contaminated with dangerous toxins from algae: “In 2011‚ bright green slime spread across one-third of Lake Erie. The slime was a harmful algal bloom‚ caused by cyanobacteria” (Kowalski 34). As a result of Lake Erie being polluted people must find the issue and resolve it. One theory of the pollution in Lake Erie is that the species are not

The emetic type is usually associated with foods that have starch in them such as rice‚ potatoes‚ cheese‚ and pasta. This illness occurs within a time frame of 1-6 hours after the contaminated food has been eaten. Symptoms of this type of illness are nausea‚ vomiting‚ and abdominal cramps.

Chemistry of Snake Venom Timothy Chapman Chemistry Accelerated Oct. 12‚ 2010 Snake venoms are something of an evolutionary marvel. Through minute mutations and changes‚ normal saliva has changed to the myriad of harmful enzymes‚ toxins‚ non-peptide organic substituents‚ small peptides‚ and inorganic and metal ions found in the venom of today’s snakes. In general‚ venom is defined as a simple to complex secretion produced in a specialized gland that is typically delivered via specialized envenomation
