I would not classify it as acid rain because an acidic pH is anything lower than 7. The question says the pH is 7.2 which is close to a neutral pH and also typical acid rain has a pH value of 4.0 so your sample probably isn't acid rain.
As far as environment, acid rain removes minerals and nutrients from the soil that trees need to grow, therefore dying plants or trees are common in areas where acid rain is frequent.
As far as human health, things that make acid rain such as sulfur dioxides and nitrogen oxides tend to have an enormous effect on our respiratory and cardiovascular health. These particles that make acid rain can cause heart attacks resulting in death for people with increased heart disease risk, and effects on lung function, such as breathing difficulties for people with asthma.
nahh.. the rain is not an acid rain.. acidic rain/water etc Ph level is below 7.. 7.2 is still considered normal.. as for the effect for the human health, it do not cause direct effect as it is not acidic enough. as for the environment, it may cause harm to the ecosystem. for example, the declination of a species of fish etc
