Residents report strange chemical odors in Hoboken, NJ

Received a few letters including the one below about a peculiar smell that has been lingering in the Hoboken air this spring.

“I’m wondering if anyone can share their thoughts, because I haven’t been able to find information elsewhere. Has anyone smelled something funny lately in the air, similar to the smell of fertilizer?

I often drive over the Pulaski Skyway, and I smell this odor most strongly around the Newark Ironbound area. However, I’ve smelled it last week as far out as Summit, and I’ve definitely smelled outside my apartment in Hoboken a few nights recently. Does anyone else know what I am talking about? If so, does anyone have thoughts on what this chemical smell is?”

411 Note: I’ve smelled this too. It does have a fertilizer like smell, but didn’t seem toxic. Could it be something as simple as pollen?
