Regular monitoring of metal concentrations in the tailing effluent is essential to ensure compliance with environmental standards and prevent pollution of marine ecosystems. For example, samples were collected at the Basamuk Refinery and analyzed for heavy metal concentrations using approved standard methods. Additionally, implementing the deep-sea tailing placement (DSTP) method for tailings disposal minimizes the impact on aquatic systems by discharging tailings well below the sea level. As seen at the Ramu Nickel-Cobalt project in PNG, the method has been effective in preventing immediate risks to the marine ecosystem. paraphrase it in ten simple english sentences

Regularly checking metal levels in the waste water is important to make sure it follows environmental rules and doesn't harm sea life. At Basamuk Refinery, samples were taken and tested for heavy metals using official methods. Using DSTP for getting rid of tailings helps protect aquatic systems by putting the waste deep under the sea. The method worked well at the Ramu Nickel-Cobalt project in PNG and kept the ocean safe. Following guidelines and monitoring levels can help prevent pollution and protect the environment. It's necessary to keep track of metal levels to make sure they don't exceed safe limits. The DSTP method is a good way to dispose of tailings so they don't harm marine life. Monitoring metal levels regularly helps ensure that the waste water meets environmental standards. The Basamuk Refinery took samples and checked for heavy metals to make sure they weren't harmful. By using DSTP, the Ramu Nickel-Cobalt project was able to protect the marine ecosystem from immediate danger.
