The ground water may become contaminated with both organic and inorganic substances which may include heavy metals like Cadmium, Chromium and Nickel, etc. (Christensen et al, 2001). Pharmaceutical wastes can cause cancer within human cells. (Krifa et al. 2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination.
When it reproduces, it generally has only two generations per year. Also, of those generations there are typically between 50 and 300 eggs produced on the underside of the branches. The balsam woolly adelgid is a very small invasive sucking insect that you can find in coniferous forests. It is
Their populations are healthy worldwide and they have no special status or protections. However, they are now considered a non-native pest species in some areas where they have been introduced. The rainbow trout (Oncorhynchus mykiss) is a species of salmonid native to tributaries of the Pacific Ocean in Asia and North America. The steelhead is a sea run rainbow trout (anadromous) usually returning to freshwater to spawn after 2 to 3 years at sea. In other words, rainbow trout and steelhead trout are the same species.
My independent variable is the green crab, which I added to the tide pool off the Washington State coast. My dependent variable was the coral weed because it is affected by the green crab. I started my experiment at 0 crabs/sq. ft. I replicated this step 5 times (resetting the simulation between each replication) and measured the population of the green grab and the coral weed at the end of each repetition.
Another is the Haleakalā Silversword, which is a unique native plant that only blooms once in its life cycle, and it lives 15 to 50 years. Some of the invasive plants are the Ginger plant, Strawberry Guava, Asparagus Fern, and Bird of Paradise. These are just some of the many beautiful plants in Hawaii. The main water supply comes from rain, and we do have reservoirs. The main one is the Waihole Water supply from the mountain run off, and an important system for irrigation.
The length of time that the species’ of bird appeared in the frame was 12.71, [pic] 17.08 seconds (the average + standard deviation). Discussion The significance of Sitta carolinesis observed at the feeder was very important to the research for future experiments. Sitta carolinesis help maintain a balance in the insect population, and dispose of seeds from a variety of plants. Whit-Breasted Nuthatches bird is common, it does not have a lot of documentation on its life history. The results of the bird living in small natural holes in trees can be a cause on why there is not a lot on their life
They like to eat fish and amphibians. This snake mates from late May to early June by forming “mating balls” consisting of one female and several males. They are live births, not hatched in eggs and have an average litter size of four up to ninety-nine but average about thirty babies. Only fifteen percent of the young survive their first year. They grow quickly, but then slow down when they approach sexual maturity, which is about two to three years.
VOCs were broken down into specific contaminants which include chlorobenzene, 1, 2, 4-trichlorobenzene, and trichloroethene (EPA, 2012). Chlorobenzene also known as mono-chlorobenzene is a toxic chemical that is frequently used in manufacturing and producing pesticides such as DDT (OEHHA, 2000). Mono-chlorobenzene can also be used in to produce other manmade chemicals such as nitrochlorobenzenes and diphenyl oxide. All chemicals listed have been used primarily to create herbicides, rubber chemicals, and one of Ciba-Geigy Corporations largest product, dye. The chemical is a colorless liquid which makes it nearly impossible to detect in water and has the ability to harm the population by inhaling the polluted air (OEHHA, 2000).
Science, Health, and Environmental Issues Pamela Ward Eng122: English Composition 2 Prof. Iris Chao October 27, 2013 Phosphates and Nitrates Phosphates and Nitrates are chemicals commonly found in water. Even though they are not harmful in small quantities, they are harmful if they exist in large quantities. Farms use fertilizers containing large amounts of nitrates and phosphates, so they can build up water near industrial-scale farms. In a body of water in which nitrate levels have risen to high levels, these chemicals can cause excessive algae growth. When the algae die and decompose, they deplete the available oxygen in the water for fish, causing them to die.
Another item pointed to pesticides, fertilizers and road salt as additional contributors to the pollution problem. And even further a New York Times article spoke about the algae blooms resulting from phosphate pollution. The lake has experienced a decline in its fish production attributed to the “dead zone” resulting from algae blooms. Further, the fish caught have ingested plastic and plastic the article argues attracts chemicals like bisphenol A (BPA) a contaminant said to affect the endocrine system. This
