N2  - Exposure to toxic contaminants in the environment harm human and an- imal health as well as disturb the integrity and function of the impacted ecosystem.The impact could belocal ,regional ,and global.The concen- tration  of a toxic substance below or above detection limits or thresholds in environmental samples is frequently recorded as non-detect ,which cre- ate a left or right censoring .Interval censoring occurs when the correct values are known only for those falling above a lower threshold and below an upper threshold.Multiple censored points are also important in prac- tice, as censoring threshold values may change overtime .In this thesis, we aim to estimate the environmental contaminants concentration and loading in the presence of censored and missing value
