Response of a Coastal Microbial Community to Olivine Addition in the Muping Marine Ranch, Yantai.

Spreading olivine powder in seawater to enhance alkalinity through weathering reactions has been proposed as a potential solution to control atmospheric CO concentration. Attention has usually been paid to the chemical properties of seawater after the addition of olivine within lab and modeling studies. However, both microbial acclimation and evolution in such manipulated natural environments are often overlooked, yet they are of great importance for understanding the biological consequences of whether olivine addition is a feasible approach to mitigating climate change.

[Study on Influencing Factors of Environmental Testing Quality of Medical Device Manufacturers Clean Workshops].

Objective: Improve the quality of testing in medical device manufacturers clean workshops to ensure the authenticity and reliability of testing data.

Methods: Analyze the problems and influencing factors found in the process of testing of medical device manufacturers clean workshops from 2016 to 2020, and put forward reasonable suggestions to ensure the quality of testing.

Results: In the process of testing, there are six factors that affect the quality of testing, including testing personnel, instruments and equipment, testing consumables, testing methods, testing environment and actual operation.
