"It is unbearable to breathe here": air quality, open incineration, and misinformation in Blantyre, Malawi.

Blantyre, Malawi's Queen Elizabeth Central Hospital (QECH), or Queen's, as it's known locally, is the country's largest public hospital. However, Queen's is not served by regular municipal waste collection. Rather, most hospital waste (infectious and non-infectious) is gathered by grounds staff and openly burned, in several constantly smouldering piles, sending up clouds of smoke.

Health benefit/burden, PM removal effectiveness, and power consumption based comparison of common residential air-cleaning technologies in the United States.

This modeling study compared the common air cleaners in U.S. residences based on averted disability-adjusted life years (DALYs) related to indoor PM concentration reduction and the DALYs resulted from carbon-di-oxide (CO ) emissions from power consumption.

Simplified empirical model for phosphorous removal in a facultative wastewater lagoon.

Nutrient removal in a facultative lagoon in Manitoba, Canada, was monitored from May 2015 to April 2016. According to the 12-month data, phosphorous concentration in the effluent did not meet the regulatory requirement. Various models have been developed to predict nitrogen removal from lagoon through the years; however, not much effort has been deployed to model phosphorous removal from lagoons.

Mechanism of nitrogen removal in wastewater lagoon: a case study.

Ammonia being a nutrient facilitates the growth of algae in wastewater and causes eutrophication. Nitrate poses health risk if it is present in drinking water. Hence, nitrogen removal from wastewater is required.
