TAILIEUCHUNG - SUMMARIES OF WATER POLLUTION REPORTING CATEGORIES

Furthermore, the particular bus in which the commuter travelled during this week was not air conditioned so ventilation was provided by open windows, allowing air to flow freely in and out of the bus. This is an interesting result as it demonstrates that due to the high temporal and spatial variability in CO concentrations, other variables (such as ventilation rate and proximity to emissions) may be more important in determining exposure than choice of transport mode. For the runner, exposures were lower than for the car and bus commuters when running along the dedicated footpath/cycleway but not significantly lower. | ATTAINS parent cause category summaries adapted from doc. no. EPA841-R-12-104 October 2012 SUMMARIES OF WATER POLLUTION REPORTING CATEGORIES This document includes summaries of 34 general reporting categories used for EPA ATTAINS data on polluted waters. The summaries were developed for non-technical audiences to explain clearly what the category is where the pollution comes from how it can harm the environment or human health and what individuals can do to help reduce the problem. These summaries of ATTAINS reporting categories also appear along with simplified common category names in How s My Waterway a localscale search application that retrieves ATTAINS data and translates it for general audiences. Simplified names from How s My Waterway appear in parentheses after the ATTAINS name in the coming pages.

EPA841-R-12-104 October 2012 ALGAL GROWTH EXCESS ALGAE can occur when too many nutrients warm water temperatures and reduced flow trigger the overgrowth of naturally occurring algae into thick mats on or in the water. Blooms of algae can harm aquatic life by clogging fish gills reducing oxygen levels and smothering stream and lake beds and submerged vegetation. .
