I didn't look into this specific place but I imagine those plus -- cars -- are enough to kill animals as small as fish. Non-gas (liquid and solid) pollution as I like to call them, from autos are plenty. Tire wear particles, random metal debris from chasis and drive-chain, fuel, oil, grease, coolant leaks, brake dust, exhaust soot, there's a whole bunch of shit coming out of them than just CO2. Truely an evil technology.
