    Introduction

    In many regions, harmful algal blooms constitute a serious environmental issue. Examples of toxic algal blooms that can have detrimental effects on people's health, aquatic ecosystems, and the economy include red tides, blue-green algae, and cyanobacteria.

    These blooms can produce incredibly harmful toxins that can make people and animals unwell or even kill them. They also create dead zones which totally damage the ecosystem.

    Chlorophyll can be found in algae which is a photosynthetic organism. A technique called fluorometry is used to measure how much light a material emits when excited using light of different wavelengths(Fluorescence).

    When Chlorophyll is seen under white light, it is green in color. But when it is seen under blue light, it will be red in color as shown in the video below. This helps us to find and detect the presence of Algae.
