a source created by human activities. Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place. Indeed, ancient human settlements are frequently recognized by their wastes—shell moundsand rubble heaps, for instance. Pollution wa...
There are several types of water quality standards. Stream standards are those that classify streams,rivers, andlakeson the basis of their maximum beneficial use; they set allowable levels of specific substances or qualities (e.g., dissolvedoxygen, turbidity, pH) allowed in those bodies of water...
With industrial plants, transport corridors, and other pollution sources disproportionately placed in low-income neighborhoods, air pollution is higher in these areas7,17,18, driving down housing prices and reinforcing their status as low-income neighborhoods19,20. Finally, constraints on healthcare ...
The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest ...
The scientists believe that the satellite SDGSAT-1 can play this role by supplementing the existing nighttime light data with multispectral and high-resolution features. The scientists used Beijing as an example, and found that their approach is highly effective in distinguishing the various types of...
Among all types of pollutants, the effect of soil pollution is considered ambiguous; however, their implications are very notable. Some other effects of soil pollution are listed below: Loss of soil nutrients, which makes the soil unfit for agriculture ...
Due to increasing offshore pollution, the stable succession and development trend of marine ecosystems has been broken. It is thus important to identify and regulate the quantity, composition and transportation of pollutants in offshore regions and their behavior in marine ecosystems. In particular, ...
Scenario B, which implements a carbon cap based on US NDC, allows for an increase in carbon emissions from 2040 to 2050 due to the policy assumptions made by the Energy Innovation Technology and Policy LLC modeling tool. Table 1 Description of decarbonization scenarios and their implemented ...
