Ortho-Nb₂O₅ quickly adsorbs methylene blue (MB) with much greater capacity than reported inorganic adsorbents. Furthermore, ortho-Nb₂O₅ has a stronger affinity to cationic dye than anionic dye because cation exchange is involved in th ...

However, in this study, we found that MeHg levels in domestic crabs in China were also relatively high (range: 50–1400 ng/g, dry weight). The high MeHg levels in crabs and their high consumption do not match the risk assessment of MeHg, indicating ...
