Abstract
In the South Coastal Forest area, West Sumatra, a luminous mushroom with the species Neonothopanus Sp. This research was conducted with the aim of seeing the effect of heavy metals on the bioluminescence reaction of luminous mushrooms. Starting from the effect of heavy metal concentrations on the intensity and inhibition coefficient of luminous mushroom biolumination. From the measurement results, the maximum intensity value of luminous mushrooms is 499.6 au occurring at a wavelength of 505 nm. At a wavelength of 505 nm, visible light is produced in green. The results obtained are in accordance with observations, because the light emitted by the glowing mushroom is green. If the concentration of heavy metals is greater, the intensity of the bioluminescent fungus (Neonothopanus sp) will decrease. The type of heavy metal affects the intensity of the fungus biolumination. The greatest decrease in intensity occurred in copper (Cu) and iron (Fe), zinc (Zn) and lead (Pb). If the heavy metal concentration is greater, the inhibition coefficient will be smaller. The greatest inhibition coefficient due to the presence of heavy metals occurs in copper (Cu) then iron (Fe), zinc (Zn) and the smallest is lead (Pb).
Highlights
Pollutant Is a condition that Is getting worse
The greatest inhibition coefficient due to the presence of heavy metals occurs in copper (Cu) iron (Fe), zinc (Zn) and the smallest is lead (Pb)
The results showed that the lower the light emission of fireflies the greater the heavy metal concentration
Summary
Pollutant Is a condition that Is getting worse. This changing situation Is caused by the entry of pollutants. According to Darmono (2001) Industrial pollutant can cause huge losses because the waste generally contains toxic substances including copper (Cu), mercury (Hg), chromium (Cr), cadmium (Cd), lead (Pb), which are often used by an industry in the production process both raw materials, catalysts and main materials [2] These metals will form inorganic and organic compounds that can damage living things. Bioluminescence in mushrooms is used to monitor environmental pollution and extraction of heavy metals. The Effect of Heavy Metal Pollutants on Bioluminescence Intensity of Luminous Mushrooms (Nenothopanus sp). Information on the effect of heavy metal pollutants in Padang City on the bioluminescence intensity of luminous mushrooms (Nenothopanus sp) using heavy metals copper (Cu), iron (Fe), zinc (Zn) and lead (Pb) has never been studied. Research is needed to see the effect of concentrations and types of heavy metals on the intensity of bioluminescence of luminous mushrooms (Nenothopanus sp)
