Turbidity

takes place in photosynthesis. Inside every lake, the light decreases as one goes deeper. After, finding all ranges of light, the ETI and the compensation were then calculated for both lakes (Tale 5). In the 2.5m to 1.7m depth in both lakes, the turbidity and algae growth has demonstrated that indicates so much the depth of compensation, such as the ETI, and can also demonstrate its specific trophic states. The TSIs calculated for each lake demonstrate that Wakefield Pond has to be considered a…

The negative effects of water pollution can be seen all throughout the United States, however, a solution for this huge issue is slowly emerging. The harmful or irritating substances in the environment are called pollutants. There are many different types of Pollution that need to be addressed, and one of them is the issue on water pollution. Contamination of water, typically by foreign matter such as microorganisms, chemicals, industrial or other wastes, or sewage. “Water pollution can be…

All the of the meat eaters in the group partook in trying some of the traditional stuffed, grilled, and smoked delicacy. It was then off to Cerámicas Seminario a ceramic workshop, where we got to see how clay pottery ceramics have continued to made and painted by hand by extremely talented local artists. The final stop of the day was at a small chicha house. Chicha or chicha morada is a sweet fermented corn or purple corn drink with a low alcohol content of about 3 percent. We each tried a…

has other rivers flowing into it so it has multiple different sources of water. The physical predictors such as habitat type, channel type, temperature, and flow rate can assess the quality. Chemical predictors such as pH, dissolved oxygen, and turbidity can also assess the quality of a stream. Thirdly, the biological predictors, such as macroinvertebrates, can assess stream quality. Macroinvertebrates can be used to assess stream water quality because they determine how polluted water is. Some…

Introduction Coral reef ecosystems are arguably one of the most biologically diverse ecosystems on Earth. (Spalding 2001) Because of the marine life that swarms these areas, the reefs are comparable to those of tropical rainforests. (Spalding 2001) Additionally they play a critical role in the success of coastal communities, providing protection from storms, and drives tourism to these areas. However, due to unfortunate changes that inundates the coral reef ecosystems from increases in human…

1. What is your understanding of the concept of climate change and the urban heat island effect? My understanding of the concept of climate change and the urban heat island effect is that they are both becoming more progressively harmful to our human health, the air we breathe, and water supply in our communities. Carbon dioxide (CO2) emitted from auto and factory emissions acts as a blanket, trapping long-wave infrared energy coming off the earth making our planet much warmer. Most radiation is…

Currently, Lagoa Vermelha has a depth of 1.0 m, with a small central core reaching a depth of 1.4 m, while Hohn et al. (1986) described a water column up to 1.70 m. In the present study, there was a greater tendency of accumulation of fine material, with little concentration of carbonates, at the highest depths. As expected, the accumulation of fine sediment was also associated with higher concentrations of organic matter. The results obtained in the bathymetric survey showed occurrence of a…

1.7.3.4. Hydrogen sulphid test (MacFaddine, 1980): Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production. 1.7.3.5. Sugar fermentation test (Willis, 1977): Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…

afternoon demonstrated to us how damaging the gold mining industry must have been in its peak. So much sediment is dislodged and flushed downstream, which affects the organism that live in the creeks that rely of specific water conditions, including turbidity, or cloudiness of the water. On a large scale, the gold mining techniques demonstrated by the family at Las Minas in Rancho Quemado would have significant environmental impacts. When the family at Las Minas stopped relying on gold…

Introduction Water is a chemical compound comprised of two hydrogen atoms and one oxygen atom and is written in the chemical equation form of H2O. Water has a tetrahedral molecular shape which is also known as tetrahedral electron pair geometry (Ophardt, 2003). This arrangement is due to valence electron pairs, mutually repelling each other at a 109.5-degree angle. This repulsion is caused by a non-bonding pair of electrons and two hydrogen atoms which in turn repel against each other to form…
