Use of biochar to produce reclaimed water for irrigation use.

Emerging contaminants, especially, pharmaceutical and personal care products (PPCPs) are not removed well during conventional wastewater treatment and hence pose water quality risk to the environment and potentially to public health. Long-term use of reclaimed wastewater for irrigation can lead to accumulation of trace contaminants in the soil, ground water and their subsequent uptake by plants and potentially can enter human food chain. This paper uses biochar as an adsorbent to remove emerging contaminants from treated wastewater by performing fixed bed experiments.

Hair dye related acute kidney injury--a clinical and experimental study.

We studied paraphenylenediamine (PPD)-related acute kidney injury (AKI) in 81 patients and also in albino rats experimentally. In the patients' group AKI was found in 32.7%.
