This correlation is very strong as the R2 value is over 0.95. The vertex of the graph lies in the point (0.69,23.084) where 0.69 is the value of the amount of water and 23.084 is the maximum achieved height. It implies that, if all the other parameters are maintained constant, a water rocket will be able to reach its maximum height when it is filled at around 34%. If it is filled excessively more or less than 34%, the rocket will fail to reach its maximum potential height. Water acts as the fuel in the water rocket, but unlike other conventional vehicles having too much of it is not recommended.
Infrared was the least efficient. It increased the level of CO2 in the biochamber. The infrared light does not contain an adequate amount of energy to affect the process of photosynthesis positively. White light contains all colors of the visible light spectrum, so as expected, it enabled to photosynthesis to occur. Ultraviolet light contains too much energy to properly and consistently assist photosynthesis.
One of the major risks in using recycled water is enteric illness. Recycled water has microbial pathogens which could cause an effect to human health. Some categories of the microbial pathogens are viruses, bacteria, helminthes, and protozoa. These pathogens could cause sickness to human health like hepatitis, amoebas, diarrhea, and many more. There are main problems arise in long-term contact with recycled water especially in rural and urban communities, recreational areas, occupational sites, schools, subdivisions, and in illegal contacts with the recycled water
Another place where the pollution of water is at the critical point is Sungai Klang where the pollution really affected the community at that place due to the stinky smell that come from the river, the smell that come from the river is caused by the rubbish that block the flow of water. The pollution in Klang also cause the water source not safe for the daily use such as for washing and drinking. Industrial waste come from the industrial, the waste from the industrial such as paper, an example of industry that give impacts to the water is paper industry as it write words, drawing and printing which they used ink. Inside the ink was the ink pigment which the pigment was not soluble in water, by taking example of white ink contain titanium oxide as the pigment. The last factors that contribute to water pollution is the ballast water tank where the ships carried water together with the organism that were placed in the ballast water tank
1. Introduction Due to the extensive use of pharmaceutical active compounds (PhACs), a wide range and different of PhAC residues occurs in the aquatic environment. Their fate is potentially a major issue that is yet to be understood .Extensive use of antibiotics for disease prevention, treatment of microbial infections and promotion of animal and plant growth have led to the frequent detection of different antibiotics and their by products in the environment [2,3]. The antibiotics distribution in the environment can increase the resistance of bacteria and subsequently compromise public health by preventing treatment of infections caused with these bacteria ; and this is one of the major challenges for human and veterinary medicine. one of the most widely used antibiotics in human and veterinary medicine is Ciprofloxacin (CIP), that is a third-generation of Fluor quinlones.
With this in place, the waters become murky and filled with substances that can harm marine life. As mentioned in Cindy Clendenon’s article, Pollution of the Ocean by Sewage, Nutrients, and Chemicals, “coasts are densely populated, the amount of sewage reaching seas and oceans is of particular concern because some substances it contains can harm ecosystems
Other types of toxic plastics are BPA. Both of these are of great concern to human health. BPA is used in many things including plastic bottles and food packaging materials. Over time the polymer chains of BPA break down, and can enter the human body in many ways from drinking contaminated water to eating a fish that is exposed to the broken down toxins. Specifically, BPA is a known chemical that interferes with human hormonal
The cause of this was a nasty toxin called microcystin. Microcystin appears because of human pollution and fertilizers that flow into rivers and lakes which then lead to the ocean. Cancer-causing chemicals called PCBs and pesticides like DDT are in marine mammals ' fatty tissues and they cause serious harm. 2. Many health departments encourage people not to swim 72 hours after it rains because the coastal waters are polluted from urban runoff, leaking sewage from sewage pipes and overflowing sewer manholes.
It is mostly screened out by ozone but that is changing with the increasing depletion of the Ozon layer. Although UV has benefits some of which are production of vitamin D, role in vision of vertebrates and invertebrates, formation of pigments in plants, it also has many negative effects. It is known that UV causes skin cancer, damages eyes and tissues and leads to different ecological effects. (Yagura et al., 2011) Consequences of UV irradiance on humans, plants, animals and the whole ecosystem are numerous. It has been shown that artificial UVC does extreme damage to exposed tissues.
