IL27

Interleukin 27 (IL-27) is a heterodimeric cytokine that includes a 4 helix package deal cytokine-like subunit, termed p28, and a soluble cytokine receptor-like subunit, EBI3 (Epstein-Barr virus-induced gene 3). The p28 subunit has homology with different single-chain cytokines, while EBI3 is expounded to the extracellular area of the hematopoietic cytokine receptor relations.

This increase in production has come with a big disadvantage, the contamination of groundwater (along with surface bodies of water and soil) by the pesticides. Because pesticides can take decades to get from the surface to groundwater, the problem with pesticides in groundwater could become worse in the future. S. Environmental Protection Agency are working to understand pesticide contamination of groundwater and to try to set standards for how much pesticide can be safely applied to the land. A scientist tests a sample of groundwater taken from a landfill in California.

The sinkhole creates a kind of water freeway; water can move easily down through the many open spaces in the rock to the groundwater zone. Sinkholes often occur in limestone rock. In states enriched in limestone, Groundwater 413 such as Iowa, sinkhole-related contamination of groundwater is a concern. In just the northeast part of Iowa, almost 13,000 sinkholes are known to exist. Groundwater can also be contaminated when underground storage tanks, such as the tanks located underneath gas stations, develop a leak.
