Photochemistry of foraminiferal test as proxy of Marine Environment, parts of Andhra Coast, East Coast of India

Abstract

The use of in-coastal environment for monitoring activities such as the marine environment is well known across the world over the years. As a representative of various water-based environmental monitoring activities, many species of foraminifera such as Ammonia have been used. The screening of foraminiferal shell for chemical constituents provides a step forward in determining the ability of benthic foraminifer in the coastal area to react to anthropogenic metal pollution. This study's initial hypothesis is the Foraminifera Calcite Test (Ammonia dentata, Asterorotalia pulchella, Elphidium crispum, Quinqueloculina laevigata, and Massilina secans) binds anthropogenic metals to the structure of the shell and initiates the deformation test. This research uses the normal and abnormal shells of Ammonia specimen. The Ponar collector was used to sample surface sediments. Sophisticated facilities like SEM (Scanning Electron Microscope), EDS (Energy Dispersive X-ray Spectroscopy), and FTIR (Fourier Transform Infrared spectroscopy) detectors have been employed for the analysis of the Foraminiferal shell. For each test (the shooting was done thrice, i.e. first chamber (proloculus), the aperture chamber, and the chambers between the two. The key elements of the foraminifera test are oxygen with an average (weight range of 44.71 - 58.79%) and carbon with an average weight range (10.07 -12.07%). There is a record low level of C element in the abnormal tests.
