Types of pesticides include substances that kill weeds (herbicides)‚ insects (insecticides)‚ fungus (fungicides)‚ rodents (rodenticides)‚ and others (Toxins). Pesticides were created to maximize crop yields by protecting the plant from possible attackers and are composed of chemicals that are dangerous (A history). Combining chemicals

Two of the predominant prevention methods include the use of Long-Lasting Insecticide-Treated Bed Nets (LLINs) and Indoor Residual Spraying (IRS). LLINs are draped over sleeping areas‚ providing a physical barrier to the user at night when mosquitoes are most active. The nets are treated with insecticides‚ which

Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food‚ for stimulating the brain‚ for providing cellular energy‚ and for repairing all tissues‚ organs‚ and cells. There are three types of enzymes: metabolic enzymes‚ digestive enzymes‚ and food enzymes. Metabolic enzymes catalyse‚ or spark‚ the reactions within the cells. The body’s organs‚ tissues and cells are run by metabolic enzymes. Without them our bodies

Biopesticides: A Better Alternative for a Healthy Future For decades‚ the metaphorical story of the “Birds and the Bees” has been told to children in order to explain sexual intercourse. Since honey bees are an important part of the fertilization process among plants‚ also known as pollination‚ this story is a good way of speaking openly about the subject without using technical terms. When a honey bee lands on a flower‚ their feet slip into little grooves that hold pollen sacks which they carry

What Causes Water Pollution? Industrial waste gets dumped into these water bodies. This causes a chemical imbalance in the water leading to death of the aquatic beings. Insecticides‚ pesticides and ripening chemicals that are used on plants run into the ground water system or nearby streams. Washing clothes near lakes and rivers causes detergents also causes a condition called “Eutrophication” which blocks sunlight from entering inside and reduces oxygen values in the water causing an inhabitable

Alternative Methods of Producing Iodized Salt | AbstractDue to the high incidence of iodine deficiency diseases (IDD) in the Philippines‚ iodized salt has become quite popular on the market. The aim of this research project is to discover different methods of making cheap and accessible iodized salt. Different gadgets were designed to mix the salt and potassium iodate (KIO3) adequately. The iodometric titration method was used to test for the iodine content of the manufactured salt. To prove

written by Rachel Carson in 1962 that discusses the effects of pesticides‚ specifically DDT‚ and how they have had a negative impact on the environment. During the time between 1945 and 1972‚ chlorinated insecticides had become widely used in efforts to protect crops. As a result‚ these insecticides had seriously reduced the populations of predatory birds‚ fish‚ snakes and other reptilian populations‚ as well as insects and other invertebrates. The decline in populations and the effects this had on

Although this is not a new disorder‚ previously called spring dwindle disease‚ autumn collapse or disappearing disease‚ there have been higher-than-usual reports of colony loss since the fall and winter of 2006 with signs similar to those of colony collapse disorder. The symptoms include the dwindling and insufficient numbers of worker bees with few or no dead bees around the colony‚ the presence of bee brood (bee larvae)‚ the presence of food‚ pollen and honey deposits that are not immediately stolen
