| T27 |
0-257 |
Sentence |
denotes |
Under an economic slowdown scenario, headwaters hundreds of kilometers away from urban areas will experience reduced deposition from nonpoint sources of pollution (regionally produced nitrogen dioxide, sulfur dioxide, ammonia, and other gaseous pollutants). |
| T28 |
258-503 |
Sentence |
denotes |
For example, given the reduction in nitrogen dioxide concentrations observed over Eastern China, Europe, the Northeastern United States, and India (Fig. 1), this is where urban surface water quality may start showing signs of temporary recovery. |
| T29 |
504-694 |
Sentence |
denotes |
Downstream surface waters may also receive less input from both point sources of pollution (e.g., industrial sites) and nonpoint sources (e.g., motorized traffic), as the lockdowns continue. |
| T30 |
695-894 |
Sentence |
denotes |
Under an economic worst-case scenario, input from other major nonpoint sources, like mining and agriculture, can potentially decline due to ripple effects created by a slowdown of the global economy. |
| T31 |
895-1095 |
Sentence |
denotes |
The effects of reduced point source inputs on surface water quality might become evident within a matter of months while the effect of reduced nonpoint source inputs could take much longer to measure. |
