A new study finds that sludge from wastewater from sewage treatment plants can be deadly to rats
The latest findings from a new study on rat health at a wastewater treatment plant in Pennsylvania suggest that the sludge produced at the facility is dangerous to humans.
The study, published this week in the journal Environmental Health Perspectives, found that rats at the plant have elevated levels of an enzyme called CCR5 that is linked to chronic health problems such as hypertension and heart disease.
In some studies, the enzyme has been linked to increased risk of cancer.
The researchers at the University of Pittsburgh School of Medicine examined the rat’s stool samples at the city-owned facility, and found that the urine samples were contaminated with an enzyme that causes a protein called C3H4 to be degraded.
C3HL4 is a member of the human blood group, which is found on the surface of red blood cells.
C3HL3 is a major component of red cells, which carry oxygen from the lungs to the heart.
The enzyme is also found on most human skin.
According to the study, rats at PSC were exposed to levels of C3HR4 at levels that were significantly higher than normal.
The researchers also found elevated levels in the rats’ urine.
“The presence of CCR4 on the feces at Psc may be a consequence of an increased exposure to C3HB, which may also be responsible for elevated C3HC levels in rat feces,” the study said.
The rats were also found to have elevated amounts of the enzyme C3HD1.
CCR1 is found in human red blood cell membranes, and CCR2 is found mainly in red blood vessels.
“Our findings suggest that CCR3 may be the main mediator of the deleterious effects of Ccr4 in rat fecal matter,” the authors wrote.
“This finding underscores the need to monitor and control Ccr3-related effects in human feces and to identify CCR6 as a potential causative agent,” they added.
“Psc has been identified as an important source of CCr4-related toxicity, which should be the focus of future studies.”
