Thunderstorms Increase Mercury Wet Deposition

Environmental Science & Technology, 2016
Mercury (Hg) wet deposition, transfer from the atmosphere to Earth's surface by precipitation, in the United States is highest in locations and seasons with frequent deep convective thunderstorms, but it has never been demonstrated whether the connection is causal or simple coincidence.

Regional Patterns of Wet Mercury Deposition

Environmental Science & Technology, 1994
Most of the mercury contamination in lakes and streams of nonindustrialized regions of the United States and Canada is derived from atmospheric deposition. In order to determine the regional patterns of these inputs, seven mercury-in-precipitation monitoring sites were established in Minnesota, North Dakota, and Michigan. A 3-year study showed that the

Wet deposition of tracer-marked aerosol

Journal of Aerosol Science, 1990
Abstract To study the import of the influential parameters on the efficiency of below-cloud-scavenging a tracer method for field experiments has been developed. To this purpose fluorescent aerosol is released at precipitation events. Precipitation samples are taken and the particle concentrations in the sample determined.

WET ACID DEPOSITION IN COLORADO

Physical Geography, 1991
Precipitation and wet atmospheric deposition patterns were investigated for Colorado for the hydrologic year 1985. Above average precipitation for the year probably gave rise to higher than average deposition of sulfates and nitrates but this potential varied by season across the state and was higher at higher elevations.

Wet and dry deposition of Chernobyl releases

Nature, 1988
The passage of the Chernobyl plume over the United Kingdom in May 1986 led to the deposition of radionuclides on the ground by wet and dry deposition processes. Here we analyse rainfall during the passage of the plume and the published monitoring data obtained afterwards, and show that levels of deposited 137Cs can be closely related to rainfall ...

Endosulfan wet deposition in Southern Florida (USA)

Science of The Total Environment, 2014
The atmosphere is an important transport route for semi-volatile pesticides like endosulfan. Deposition, which depends on physical-chemical properties, use patterns, and climatic conditions, can occur at local, regional, and global scales. Adverse human and ecological impact may result.

Observations of mercury wet deposition in Mexico

Environmental Science and Pollution Research, 2013
We provide a longer-term record of Hg wet deposition at two tropical latitude monitoring sites in Mexico, selected to provide regionally representative data. Weekly wet deposition samples were collected over 2 years, from September 2003 to November 2005. Based on this data set, we discuss the magnitude and seasonal variation of Hg in wet deposition and
