Measurement report: Development of a portable peroxy radical measurement system and application for diagnosing local ozone formation and transport

Abstract. Atmospheric total peroxy radicals RO2* (RO2∗=HO2+∑RO2) play central roles in tropospheric chemistry, governing the formation of ozone and secondary aerosols. However, due to their extremely low concentrations and high reactivity, direct observation of RO2* remains chall...

Physiological, Transcriptomic, and Metabolomic Insights into Ammonia-Nitrogen Stress in the Hepatopancreas of Litopenaeus vannamei Acclimated to Low Salinity

Elevated ammonia nitrogen significantly reduces the survival rate of Litopenaeus vannamei under low-salinity conditions. Low-salinity culture is widely adopted in shrimp farming but susceptible to ammonia accumulation; however, relevant studies mainly focus on juvenile shrimp und...
